In FIG. 5, a sample holder 10 is inserted through a lens barrel and supported by a sample stage 1, and its tip A
Is in contact with a support 12 interposed between the support 12 and the X-direction drive portion 13 inserted from the opposite side. Sealing between the atmosphere side and the vacuum side of the sample holder 10 is performed by O-rings 14 and 15. The sample holder 10 is supported by a spherical bearing, and its tip A moves in an arc around a fulcrum 9, and at this time, the support 12
Is interlocked around a fulcrum B, which is an engagement point with the X-direction drive unit 13, so that the sample 11 can be moved in the Y-direction and the Z-direction. Further, movement in the X direction (holder axial direction) is performed by the X direction drive unit 13, and movement to the vacuum side (left side in the drawing) is performed by atmospheric pressure. Sample holder 10
The support 12 connecting the fulcrums A and B between the tip of the X-direction drive unit 13 and the X-direction drive unit 13 transmits the force of the X-direction drive unit 13 to the sample holder and suppresses the vibration coming from the outside through the sample holder 10. Playing a role.

The moving mechanism of the sample holder 10 is supported by the mounting flange 2, and the driving means (not shown) drives the Y-direction moving knob 6 and the Z-direction moving knob 7 to insert the sample holder movably. The sample holder 10 is pushed through the moving block 5 which is a holding cylinder to rotate the point A around the fulcrum 9, and the sample 11 is moved in the Y and Z directions. At this time,
A return force is applied by a spring 8 arranged to face the Y-direction moving knob 6 and a spring (not shown) also arranged to face the Z-direction moving knob 7. When the tilt drive gear 4 is rotated, the tilt block 3 engaged with the tilt drive gear 4 rotates about the axis TT, and the sample is tilted.
